The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The following embodiments can be applied to the vehicle remote diagnosis system shown in fig. 1, where the vehicle remote diagnosis system shown in fig. 1 includes a vehicle after-market terminal, a remote server, a vehicle, and a user terminal, and the remote server is respectively connected to the vehicle after-market terminal, the vehicle, and the user terminal in a communication manner.
The vehicle after-sale terminal can be a mobile phone, a computer, a tablet and other terminals of an after-sale technician, the user side can be a mobile phone, a computer, a tablet and other terminals of the user, the remote server can be a cloud server or a background server, the vehicle comprises a vehicle-mounted communication module (hereinafter referred to as T-BOX), and the vehicle after-sale terminal, the user side and the uniform T-BOX can be in communication connection with the remote server based on a 4G or 5G network.
The T-BOX establishes communication connection with a remote server, is beneficial to uploading the running data of the body parts of the vehicle to the remote server in real time or at regular time, and the historical running data of various body parts of various vehicles are stored in the remote server;
the vehicle after-sale terminal establishes communication connection with the remote server, so that historical operation data of a corresponding fault vehicle body part required by current diagnosis can be downloaded from the remote server when a diagnosis request is initiated;
the communication connection is established between the user side and the remote server, so that the user side can log in the remote server to check the historical operating data of each vehicle body part of the vehicle, meanwhile, the verification can be carried out when the after-sale terminal of the vehicle requests to download data from the remote server, the after-sale terminal of the vehicle is allowed to download data from the remote server only after the user authentication is passed, the key data is prevented from being stolen maliciously, and the safety of data storage is improved;
the user side can be in communication connection with the vehicle after-sale terminal based on a 4G or 5G network, so that the vehicle after-sale terminal can conveniently push remote diagnosis results and/or maintenance suggestions to the user side.
It should be noted that the configuration shown in fig. 1 is not intended to be limiting, and in other embodiments, the vehicle remote diagnostic system may include fewer or more components than shown, or some components may be combined, or a different arrangement of components.
Example one
Referring to fig. 2, a vehicle remote diagnosis method according to a first embodiment of the present invention is shown, which is applied to an after-market vehicle terminal, and the after-market vehicle terminal is in communication connection with a remote server, and the method specifically includes steps S01-S04.
And step S01, when a diagnosis request triggered by an after-sales technician is received, obtaining diagnosis information in the diagnosis request, wherein the diagnosis information comprises the fault description of the vehicle by the user.
The fault description can be a fault description of remote communication between the user and the after-sales technician, that is, when the vehicle has a fault, the user can communicate with the after-sales technician in a remote communication manner, and the user reports the fault description to the after-sales technician. After-sale technicians can input the fault description into the vehicle after-sale terminals, and the vehicle after-sale terminals automatically trigger corresponding diagnosis requests.
And step S02, determining the fault vehicle body component corresponding to the diagnosis information according to the diagnosis information.
It should be understood that, since the user must express the vehicle body component with the fault when describing the fault, for example, when the fault is described as "the skylight is opened abnormally", the vehicle body component with the fault is the "skylight".
And step S03, obtaining historical operation data of the fault vehicle body part from a remote server, wherein the historical operation data is uploaded by a vehicle-mounted communication module of the vehicle.
In specific implementation, the T-BOX of the vehicle is connected to a power CAN network (PCAN), a chassis CAN network (CCAN) and a vehicle body network CAN (bcan) of the vehicle through a central gateway (e.g., a Central Gateway (CGW)), that is, connected to a vehicle CAN bus to obtain a vehicle data stream, where the vehicle data stream includes a CAN bus message, a DTC (Diagnostic trouble code) and GPS position information during vehicle driving, and the CAN bus message includes operation data (i.e., historical operation data) of each vehicle body component, such as a sunroof opening time and an instruction for triggering opening. The CAN bus message, the DTC (Diagnostic trouble code) and the GPS position information in the vehicle running process are sent to a remote server through a 4G network according to certain configuration.
Therefore, under the condition that the fault vehicle body component is known, historical operation data corresponding to the fault vehicle body component can be obtained from the remote server by taking the fault vehicle body component as the mark, wherein the historical operation data is also called operation data uploaded before the current time node.
And step S04, diagnosing the fault of the vehicle according to the historical operation data, and pushing the diagnosis result to the user.
It should be noted that, since the historical operation data of the faulty vehicle body component includes all data in the previous operation process of the faulty vehicle body component, for example, the historical operation data of the sunroof includes an opening time and an opening instruction, a closing time and a closing instruction, etc., the reason that the faulty vehicle body component sends the fault can be diagnosed according to the historical operation data, for example, for the fault of "abnormal opening of the sunroof", a trigger instruction (a signaling for triggering abnormal opening of the sunroof) for abnormal opening of the sunroof can be found according to the abnormal opening time of the sunroof, so that the fault diagnosis of the vehicle is completed, and the diagnosis result and/or the maintenance advice can be remotely pushed to the user side.
In summary, in the vehicle remote diagnosis method in the above embodiment of the present invention, the historical operation data of the vehicle body component of the vehicle is uploaded to the server, when the vehicle has a fault, the user may feed back a fault description with an after-sales technician, and then the after-sales technician may initiate a diagnosis request at the after-sales terminal of the vehicle to obtain the historical operation data of the faulty vehicle body component from the remote server, and perform remote diagnosis on the fault of the vehicle according to the historical operation data. Meanwhile, the remote diagnosis is triggered by an after-sales technician, and a user only needs to describe the fault, so that the user experience can be greatly improved compared with the traditional mode that the user needs to participate in the whole process in the remote diagnosis.
Example two
Referring to fig. 3, a vehicle remote diagnosis method according to a second embodiment of the present invention is shown, which is applied to an after-market terminal of a vehicle, where the after-market terminal of the vehicle is in communication connection with a remote server, and the method specifically includes steps S11 to S17.
And step S11, when a diagnosis request triggered by an after-sales technician is received, obtaining diagnosis information in the diagnosis request, wherein the diagnosis information comprises the fault description of the vehicle by the user.
And step S12, recognizing the keywords in the diagnosis information by using a character recognition technology.
In step S13, a faulty vehicle body part is determined based on the recognized keyword.
Step S14, obtaining the identification information of the vehicle from the diagnosis request.
The identification information of the vehicle may be, but is not limited to, a frame number, a license plate number, an engine number, etc., and the identification information of the vehicle may be added to the diagnosis request by an after-sales technician or embodied in the fault description by a user.
Step S15, sending a request for downloading the historical operation data of the faulty vehicle body component corresponding to the identification information of the vehicle to the remote server.
It should be understood that since the remote server stores the historical operation data of the body parts corresponding to different vehicles, the historical operation data of the faulty body part of the faulty vehicle needs to be accurately acquired based on the identification information of the vehicle.
And step S16, receiving the download data sent by the remote server according to the download request, and obtaining the historical operation data of the fault vehicle body component.
And step S17, acquiring a triggering instruction when the fault action occurs to the fault vehicle body component from the historical operation data.
And step S18, determining the fault reason of the vehicle according to the triggering instruction.
For example, in 2020, after 20 customer complaints suddenly appeared about the automatic opening of a sunroof of a vehicle, resulting in a complaint that the vehicle was flooded. But when the maintenance station is checked, all the vehicle skylight states are normal, and the locking problem can not be achieved all the time. After the vehicle is locked, the skylight historical data of the vehicle is called, and a vehicle door lock signal, a skylight state signal, a time signal and the like are screened out by an after-sales team, so that two conditions exist in the process of locking the vehicle, namely, the skylight is closed before the vehicle is locked, but the skylight is immediately opened after the vehicle is locked, and a client does not find a direct vehicle leaving; and the other is that the vehicle is suddenly waken up in the process of parking and sleeping again, and the skylight is opened. The historical data of the skylight is analyzed and found, the reason for triggering the skylight to be abnormally opened is that the remote control key unlocking button is pressed for a long time (namely a triggering instruction), the skylight is abnormally triggered to be opened when the remote control key unlocking button is pressed for a long time through actual simulation in a factory, and further the skylight is opened only by remote control through combing and analyzing, but the functions of closing the skylight and opening the window by remote control are not realized, so that a client cannot timely find the skylight after the client mistakenly triggers the skylight opening function. In contrast, after-sales groups review and optimize the skylight opening and closing strategy, and the problem is fundamentally solved.
Further, in some optional cases of the present embodiment, after the step of sending a request for downloading the historical operating data of the faulty vehicle body component corresponding to the identification information of the vehicle to the remote server, the method may further include:
and when the fault vehicle body part is a preset vehicle body part, pushing data downloading verification prompt information to the user to prompt the user to log in the remote server to verify the downloading request, so that the remote server sends data to the vehicle after-sale terminal after passing the authentication.
The preset body part can be a key body part (such as an engine) of a vehicle, a body part related to user privacy (such as a vehicle-mounted Bluetooth module, a central control instrument module, a GPS positioning module and the like), a body part set by a user or a body part specified by a manufacturer/after-sale. That is, in this case, when the failed component is the preset vehicle body component, the after-market vehicle terminal pushes the data download verification prompt information to the user side while or after sending the download request to the remote server, so as to prompt the user to log in the remote server to verify the download request, so that the remote server sends data to the after-market vehicle terminal after passing the authentication, that is, the after-market vehicle terminal is allowed to download corresponding data from the remote server only after the user passes the authentication, thereby preventing the key data from being maliciously stolen, and improving the security of data storage. The method for verifying the download request may be, but is not limited to, password verification, confirmation verification, and the like, that is, after the user logs in the remote server, a verification prompt of the download request is popped up, and based on the verification prompt, the user may select to input a password for verification, or may directly click "confirmation" to complete verification.
